Missing File or User - Certification Exam

I have done the certification exam 5 times so far, but still fails with the same reason: Missing file or user.
I zip the file using win rar and then changing the prefix from .rar to .zip.
I am not sure what I am doing wrong.
Could anybody help please?

Thank you

may i know who we are uploading the file here
like the file type with which we upload
Cheers @Vilma

I zip the folder with the workflows (xaml) inside. The file type of the zipped folder is .zip
I upload it here: https://certificate.uipath.com/account/login

hmm thats correct.
if we right click on that zip file is that having EXTRACT HERE option,
and does the zipped file has the correct project file
and kindly check whether the file size is more than the limt they have mentioned


Extract here extracts the contet of the folder correctly.
The size of the folder is 300KB

kindly raise a ticket on this
they would surely help you out
